I tried to edit my VM, but then it overshot the character limit by a lot, SO HERE'S ANOTHER ONE! With the stuff I wanted to say in addition to the old one with stuff too(hope you don't mind reading...)
Since you like Undertale check out Pony Island, don't be fooled by the name, but like with Undertale I'll say the thing that everyone always does, no looking up stuff or whatever, either buy the game or watch a let's play right away(will provide the link of the one I watched). The games are rather different but you'll see familiar elements, I wanted to call them cliches, but Undertale is fairly new and has no cliches yet. Oh yes, Bakphoon watched it too and lol'd and Trickster said he'll consider, and since unlike Trickster you do not have about 15 games he does not find time to play because apparently he's busy playing Civilization, you can totally check it out because it is ~90 minutes long, so like Undertale, a short game.
Linky link I suggest this one, the commentary makes funny moments funnier and other ones even more entertaining.
